B.A.P Brings Folky Harmonica for Acoustic Single "Where Are You?"

Looking rather inspired by One Direction, the K-pop boy band bring new video that one can't help but smile at

As a band that has typically showcases a darker image, B.A.P returns at their most cheerful with a new acoustic single "Where Are You?"

Opening with a bluesy harmonica riff, acoustic guitars and light percussion back the boys' bouncy, bubblegum-pop melodies. Even verses from B.A.P rappers Yongguk and Zelo are approached with lightheartedness. In place of a vocal hook line, the track opts for a folky whistle line that is just as effective and catchy.

B.A.P's latest draws from recent Top 40 trends, making it accessible to a wide audience: The harmonica proved to be a successful integration earlier this year via Pitbull and Kesha's Billboard Hot 100 No. 1 "Timber"; the folk-inspired whistling has been a favorite for twee indie-rock tracks (Peter Bjorn And John's "Young Folks") and pop smashes (Maroon 5 and Christina Aguilera's "Moves Like Jagger").

With what looks like a One Direction-inspired concept, the accompanying video was filmed in London and sees the guys donning brightly colored, preppy-yet-fashionable clothes. The B.A.P boys dance and skip around the city, riding a double-decker bus and making silly faces at the camera.

The video is one of B.A.P's most enjoyable for fans, with their group bromance on full display with loads of smiles, dorky play fighting and, most memorably, the band bobbing their heads in beat to the whistling

Despite a packed schedule, B.A.P likely found time to film the video while in England for a London date during their Live on Earth 2014 Continent Tour. To date, the boys brought their show to Europe, Australia Asia and North America for four U.S. dates.
